Upon completion of their course work, the students will be able to

  • Design programs, policies and/or interventions intended to improve health services and health status of individuals, communities, and populations
  • Conduct research, including formulation of specific research aim, conducting a literature review and formulating a hypothesis and selecting appropriate methodologies related to the emphasis
  • Implement strategies to prevent and control infectious diseases
